Note: Dirt and foreign material are the worst enemies of any lubricating system.

Procedure

1. Use a manual pump with a gauge. Fill the pump with clean, filtered lubricant common to the

system. Connect the manual pump into the inlet of the primary divider valve and slowly

operate pump. If system will not cycle freely below 1,500 PSI, see Step 2.

2. With pressure on the primary as outlined in step 1, remove one at a time each supply line

(if the supply lines cannot be removed, remove outlet fittings starting from the bottom and

working towards the valve inlet) and attempt to operate manual pump after each line is

removed. Do not exceed 2,000 PSI. If pressure drops and primary cycles freely after a line

is removed then blockage is downstream in the area that is being served from that outlet.

See Step 3. If all feed lines are removed and primary will not cycle, blockage is in this

divider valve. Note: When a feed line of a blocked area is removed a small shot of trapped

lubricant will usually surge out of this outlet as the inlet pressure on the divider valve drops.

If testing in Step 2 indicates a blockage in the primary divider valve, this divider valve must

be replaced.

3. Testing accomplished in Step 2 has indicated the blockage is downstream of the primary

divider valve. Reinstall the feed line into the primary valve and proceed to downstream

secondary divider valve and repeat step 2 on the secondary valve. If lubricant can be

discharged freely through the secondary valve, the blockage is in the supply line between

the primary and the secondary valve.

4. If high pressure exists on one of the secondary outlets, blockage has been located. Look

for crushed line, tight bearing, improperly drilled fittings and/or lube inlet port. Correct as

necessary.

Contamination

If dirt, foreign material or any other form of contamination is found as the source of the

blockage, clearing the blockage will only temporarily solve contamination blockage problems.

The source of the contamination must be eliminated for satisfactory service. The

reservoir must be inspected and cleaned if necessary. The reservoir filling method should be

reviewed to eliminate any chance of foreign material entering the reservoir during filling. All

lubricating systems require filtered lubricant.

Grease Separation Blockage

If a hard wax or soap like material is found in the valve outlets, grease separation is occurring.

This means that the oil is being squeezed from the grease at normal system operating

pressure and the grease thickener is being deposited in the divider valve. Cleaning the divider

valve will usually result in only temporarily solving the problem. Consult your lubricant supplier

for recommendations on alternate lubricants and your local Lincoln Distributor to verify

compatibility with centralized lubricating systems
